LUBRICATING COMPOUND.

To all whom it may concern:

Be it known that I, FREDERICK T. MANLEY, a citizen of the United States,residing in Houston, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in Lubricating Compounds,of which the following is a specification.

This invention relates to the preparation of solid lubricants intendedparticularly for use in driving journals and for other heavy bearingsworking at high speed.

The invention contemplates the production of a suitable lubricatingcompound that will. be in the form of a cake or solid at ordinarytemperatures but which will read ily feed onto a bearing. It is anobject of the invention to greatly reduce the cost of producingcompounds of this nature by utilizing certain cheap materials which havenot hitherto been used in the manufacture of this type of lubricants.More specifically it is an object to use certain asphaltic procluctswhich not only reduce the cost of mak ing the compound but addmaterially to the lubricating value of the product.

In accordance with my invention I take a high boiling paraflin etroleumproduct such as a cylinder stool; and mix it' with an asphaltic residuesuch as a viscous residue obtained from the distillation of Gulf Coastor other asphaltic base crudes. The compounded mineral oil is then mixedwith a suitable soap such as soda soap to form a solid lubricatingcompound. The proportions of cylinder stock and asphaltic residue may bevaried somewhat according-to the type of product desired but ordinarilythe proportion consists substantially of equal parts of each. Theproportion of asphaltic residue may be increased to a certain extent butif too great a proportion of this material is used the product will tendto be friable andnot suited for lubricating purposes.

As a specific example of my invention I may give the following:

Graphite"; 00. A

Application filed October 1, 1920. Serial No. 414,083.

It will be noted that in the example given a small quantity of graphitewas included in the compound but the graphite is not essential and maybe omitted if desired. Any suitable soap may be used.- For example, analkali soap, such as soda soap, or a mixture of an alkali soap and leadsoap, may be employed in preparing the compound. oil content and soapmay be so proportioned as to give a mixture of the desired degree ofhardness.

The asphaltic base oil used may be any suitable asp'haltic residue thathas been reduced to the consistency of flux oil. It may contain greateror less proportions of oxidized oil and may be composed of asphaltdissolved in an asphaltic base residue. The use of the oxidized oilseems to yield. a product of exceptionally good lubricating value.

What I claim is 1. A solid lubricant comprising a soap, a paraflin basecylinder stock, and an asphaltic base residue.

2. A solid lubricant comprising a soap composition having for itsmineral oil content substantially equal quantities of paraffin basecylinder stock and asphaltic base residue.

3. A solid lubricant comprising a soap, a parafiin base cylinder stockand asphalt dissolved in an asphaltic base residuum.

4. A solid lubricant comprising in quantity approximately fatty oil, 10%caustic soda, 10% water, 15% paraflin base cylinder stock, and 15%asphaltic base residuum.

5. A solid lubricant comprising in quantity approximately 50% fatty oil,10% canstic soda, 10% water, 15% parafiin base cylinder stock 15%asphaltic base residuum, and a trace of graphite.

In witness whereof, I have hereunto set my hand this 17th day ofSeptember, 1920.
